Regardless from your english, the set itself is pretty terrible. Its coverage is ass, and more important, the heavy recoil of Light of Ruin compromises the supposed duraility that CM and Synthesis should provide. The best bet of Floette is a Choice Specs wallbreaker with LoR, Psychic, Moonblast and HP Ground/Fire. Psychic is needed for hitting Poison types, while HP Ground and Fire hit Steel types. Moonblast is used for having a reliable STAB that doesn't let you take unnecessary rec oil.
